Arousal to spying on others for sexual gratification. Voyeurism is getting sexual excitement from watching others when they are naked or engaging in sex acts. Voyeurism is the sexual interest in or practice of watching other people engaged in intimate behaviors, such as undressing, sexual activity, or other actions usually considered to be of a private nature.
The term comes from the French voir which means "to see". A male voyeur is commonly labelled as "Peeping Tom" or a "Jags", a term which originates from the Lady Godiva legend. However, that term is usually applied to a male who observes somebody secretly and, generally, not in a public space.
Exhibitionism is enjoying people viewing (or potentially viewing) you having sex or masturbating. It could refer to public sex, having sex in the window, or having sex on live webcam for internet viewers. Exhibitionism is inherently risky, but it’s incredibly thrilling for many fetishists!
Exhibitionism is the act of exposing in a public or semi-public context those parts of one's body that are not normally exposed – for example, the breasts, genitals or buttocks. The practice may arise from a desire or compulsion to expose themselves in such a manner to groups of friends or acquaintances, or to strangers for their amusement or sexual satisfaction or to shock the bystander. Exposing oneself only to an intimate partner is normally not regarded as exhibitionism. In law, the act of exhibitionism may be called indecent exposure, "exposing one's person", or other expressions.
